I llpplicatlcn filed July 16, 1903. Serial No.165.768. (No model.)

To all whom it may concern:

Be it known that I, PHILIP A. MYERS, a citizen of the.United States, residing at Ashland, in the county-of Ashland and State of Ohio, have invented certain new and useful Improvements in Hay-Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in [O hay-tools, and more specifically to what are known as compression-sling attachments, being in the nature of a device for use in connection with a sling to enable the same to be used in connection with a carrier in the place [5 ofafork.

The object of the invention is to provide a device which may be used in connecting any form of an ordinary hay-carrier without making any change whatever except disconneete 2o ing the hay-fork from the fork-pulley and substituting the attachment which I have 'devised, using the same in connection with a suitable sling.

To these ends my invention consists in cer- 2 5 tain novel features which I will now proceed to describe and will then particularly'point out in the claims. 7

In the accompanying drawings, Figure 1 is a perspective view of a structure embodying my invention in one form. Fig.2is a vertical sectional view of the same, taken on the line a; 00 of Fig. 3 and looking in the direction of the arrows. Fig. 3 is a vertical section View taken on the line y y of Fig.2 andloolb 5 ing in, the direction of the arrows. Fig. .4 is

a perspective view illustrating the device applied to a sling, showing the position of the parts at the beginning of the operation of compressing the bundle; and Fig. 5 is a simi- 4o lar view showing the position of the parts after the fork-pulley has passedthrough the attachment, the bundle being compressed.

, Referring first more particularly to Figs. 1, 2, and 3, which show the attachment in de 5 tail, it may be stated that while these details,

which I will now proceed to describe incidentally to the description of the general structure of the device, are deemed desirable features the present invention is in no way restricted to said details of construction.

The attachments co1nrise"a bail o1' loop 1,

having the form of a yoke or arch and pref erably made in two separate pieces united by screw-bolts 2 and 3. The arched end of-the bail, which may for convenience sake be termed the lower end, is provided with a projection 4, terminating in a hook 5, and it is at this end that the screw-bolts? are located. The separated ends of the parallel arms of the bail at what may be conveniently termed the upper end of the attachment are united by the screw-bolt 3, which is provided at eachend with a nut'6, seated in a recess 7 in the center of a disk-like enlargement 8 at the end of each arm of the bail.

I A sleeve 9 surrounds the bolt 3 and serves as ploy a'pivoted arm 13,- servingboth as a separator to separate the leads of the rope and as a support for the guide-pulleys, over which said leads travel during a portion of the time. This arm is pivotally connected with the bail orloop near that end thereof which is provided with the roller, and I prefer to'pivot it on the same axis as said rollerto wit, the sleeve ,9 andbolt 3. is in the form of 'a U -shaped frame having To this endthe arm 13, which two parallel members 14 and a cross or connecting piece 15, is provided at the upper ends 'of the members 14, with annular portions or eyes 16, which fit upon the sleeve 9 between the rollers 10 and 11, as shown in' Fig. 2. Near its other or lower end'the arm 13 is provided on each side with a guide-pulley 17, supported in a bracket 18, preferably integral with the arm 13. Each bracket 18 preferably extends some distance beyond its pulley, as indicated at 19, to form a guard therefor and to maintain the rope in proper position on the pulley. It will be noticed that the guide-pulleys 17 are located at some dis tance from the roller and at or near the opposite end of the arm from that nearest the roller.

Provision is made for locking the arm 13 in the central position relatively to the loop or bail 1, (shown in Figs. 1 to 4, inclusive,) and for this purpose I prefer to employ a locking-bolt 20, adapted to slide longitudinally of the arm in suitable guideways therein. These gnideways are formed in the present instance by an aperture 21 in the connectingpiece 15 of the arm 13 and an aperture 22 in a cross-piece 23, forming a part of said arni 13. That portion of the bolt 20 which passes through the aperture 21 is preferably rectangular in cross-section, the aperture 21 be ing similarly shaped to fit the bolt and prevent its turning. The rear end of the bolt 20 is in the form of a cylindrical shank 24 of reduced diameter, fitting the aperture 22, which is made circular for this purpose. The reduction of the shank forms on the bolt a shoulder 25, which shoulder constitutes an abutment for one end of a spring 26, coiled around the shank 24 of the bolt and bearing at its other end against the cross-piece 23 as an abutment. A pin 27, passing through the shank 24 above the cross-piece 23, may be employed to limit the outward movement of the bolt before the tripping device, hereinafter referred to, is applied thereto or in case the tripping device becomes broken. Cooperat ing with the bolt 20 is an aperture 28 in the inner face of the loop or bail 1, so that the engagement of the boltin said aperture locks the arm 13 in central position. To make the bolt self-locking, its end is rounded or beveled, as indicated at 29, and the inner surface of the bail 1 is similarly rounded or beveled at each side, as indicated at 30.

The tripping device, hereinbefore referred to, consists of two plates 31, pivoted on an axis 32, carried by the arm 13 in the upper portion thereof, said plates extending downward between and past the pulleys 17 and having their marginal portions bent outward,- as indicated at 32. These plates are connected by means of a V-shaped cam-piece 33,

. by which they are rigidly united; and, in fact,

said plates and cam-piece may be considered as a single piece and may be so constructed, said parts constituting the trip-arm. I The cam-piece 33 passes through a slot 34 in the rectangular body portion of the bolt'2O and said cam-piece bears against a roller or other suitable abutment 35, carried by the bolt 20 within said slot. In the present instance I have shown the abutment as consisting of a roller 35, as just stated, said roller being carried by a pin 36, which may be placed in any one pair of a series of apertures 37, formed in the bolt 20 to receive the same. By shifting the pin 36 the tension of the spring 26 may be varied, as well as the extent to which the bolt 20 projects into the aperture 28. To accommodate a maximum amount of projection of the bolt and at the same time save in the desired manner.

metal and lighten the casting, the projection 4 may be hollowed out to form a chamber, as indicated at 38.

It will be noted that when the arm 13 is locked in a central position the roller 35 bears in the center or angle of the V-shaped cam-piece If pressure he applied to either one of the plates 31, so as to move the triparm in one direction or the other, the campiece will bear against the roller 35 in such a way as to force the bolt 20 back and withdraw it from the aperture 28, thus unlocking the arm 13.

In Figs. 4 and 5 I have shown my improved attachments as connected to a sling and operating in connection with a fork-pulley and rope of a hay-carrier of ordinary construction. One end of the sling (indicated by the reference-numeral 39) is connected to the hook 5 of the attachment. The other end of the sling (indicated by the reference-numeral 40) is connected to the book 41 of the forkpulley 42.- The rope leading from the fork to the carrier is indicated by the referencenumeral 43, and it will be seen that during the first portion of the operation of drawing the sling around the bundle of hay the two leads of the rope 43 travel around the guidepulleys 17, being separated by the arm 13, so as to keep the leads clear of each other and cause them to run freely around said guidepulleys. During this portion of the operation the rope 43 does not run on the roller at the end of the yoke, but on separate guidepulleys located at some distance from said roller. As the bundle is compressed the fork pulley 42 approaches the attachment and finally strikes the tripping-arm. In this connection it will be noted that the tripping-arm is in duplicate, having a contact-plate 31 on each side of the attachment, so that the attachment is reversible, and it makes no difference which side is presented to the advancing fork. In practice these fork-pulleys are usually provided with a so-ealled registering head 44, and it is this head that first strikes the tripping-arm. The flange 32 of the tripping-plate 31 is of material advantage in this connection in preventing the end of the fork-pulley from sliding or glancing oil? of said plate without moving the tripping-arm When the trippingarm is thus struck, it withdraws the bolt 20 in the manner already described, and thus frees the arm 13, which will swing up out of the way, as indicated in Fig. 5, and will leave the loop or bail 1 free and unobstructed in its interior to permit the passage through the same of the fork-pulley 42. After the forkpulley has passed through the loop, the rope or bridle 40, which constitutes the end of the sling attached to the forkpulley, travels over theroller at the end of the loop in the usual manner.

In attachments of this character as hereto: fore constructed the fork-pulley rope 43, the fork itself, and the bridle-rope 40 have all granted to me February 4, 1896. While such a construction is a satisfactory one as a rule, the'diversity of hay-carriers and the diiferent sizes and shapes of their fork-pulleys are such that in practice thefork-pulley has been found to occasionally lodge upon the roller or in the bail, thereby preventing it from passing through the bail and moving on up to the carrier, where it should register or lock itself in the manner usual in devices of this description. My improved attachment provides a remedy for this difliculty in that the leads of the fork-pulley rope are first carried around guide-pulleys separate and distinct from the roller and located at a considerable distance therefrom in advance thereof, so.

- passes freely through said opening in the bail and does not have to be dragged around the roller at the end of the bail. In this way lodging of the fork-pulley against the roller or against the body of the bail is prevented, and the attachment is thus adapted for use in connection with a wide range of fork-pulleys of dilferent sizes and shapes and is, in fact, successfully operative with any devices of that character on the market.

I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described and shown in the accompanying drawings, as. said details may he obviously modified without departing from the principle of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
